예비교사의 직·간접 장애 경험에 따른 장애 인식 및 통합교육 태도와의 관계 모형 개발
오원석,박비주 국립특수교육원 2012 특수교육연구 Vol.19 No.2
본 연구는 예비교사들의 장애 관련 직접 및 간접 경험이 장애 인식 및 통합교육 태도에 미치는 영향을 알아보기 위한 것으로 예비교사 386명을 대상으로 수행하였다. 예비교사들의 직접 경험의 내용은 통합교육 참여 경험, 장애인과의 활동 경험 그리고 장애 친구 및 친척의 유무로 설정하였으며 간접 경험의 내용은 영화나 책 등을 통한 경험을 포함하였다. 예비교사들의 장애 인식을 알아보기 위한 척도는 오원석(2011)의 연구에서 활용한 장애인에 대한 불편함 인식 척도를 활용하였으며, 통합교육 태도는 Wilczenski(1992)가 개발한 ATIES를 활용하였다. 연구 결과에 따르면 예비교사들의 장애 인식은 대체로 양호한 수준이며, 성별이나 전공에 따라서 차이를 보이지는 않았다. 그리고 통합교육 태도에 있어서 행동장애학생과 중도장애학생의 통합에 대해서는 부정적 태도를 보였으나 경도장애학생의 통합에 대해서는 긍정적 태도를 보였다. 또한 직접 경험과 간접 경험 정도와 장애 인식 및 통합교육 태도 간 관계 모형에서는 직접 경험의 정도는 장애 인식 및 통합교육 태도에 긍정적 상관을 갖지만, 간접 경험은 통합교육에 대한 태도에 부적 상관을 갖는 것으로 제시되었다. 이에 따라 예비교사를 위한 특수교육 관련 강의 구성에 대한 제안점을 제시하였다. This study was based on the direct and indirect experience of disability awareness of prospective teachers and the impact on the attitude of integrated education which was performed on 386 people. Prospective teachers participate in direct experience of integrated education, disabilities and activity experience. The contents of indirect experience included the presence of friends and relatives and even experiences through movies and books. Regarding the preliminary measure of disability awareness for teachers, a research study by Oh Won Seok(2011) utilized recognized scales to measure discomfort for people with disabilities. In addition, a research study by Wilczenski(1992) utilized ATIES to measure attitudes towards inclusive education. According to a preliminary study on prospective teachers, disability awareness was at a generally good level and differences were observed depending on gender or majors. The attitude of students regarding behaviorial integration training showed negative attitudes. But, the attitude of the disabled students regarding the integration of student with disabilities showed a positive attitude. In addition, the degree of direct experience in disability awareness and inclusive education had positive attitudes. On the contrary, indirect experience attitudes about inclusive education presented as having negative correlation. But, prospective teacher special education related lecture configuration should provide opportunities for direct experience. These on-site observations of integrated classes gives a more desirable opportunity to have hands-on experience.
국제물품매매계약(國際物品賣買契約)에서 매수인(買受人)의 물품검사시기(物品檢査時期)
오원석,Oh, Won-Suk 한국무역상무학회 2003 貿易商務硏究 Vol.20 No.-
The time of examination of buyer in international sales contract is very significant, because the time is related with the period of claim in buyer's aspect. From the legal point of view, the time of delivery, the time of examination and the time of quality decision should be in accord. But the buyer, whose main place of business is located in importing country, wants to examine the goods in his own country. Therefore in CIF or FOB Contract, the place of delivery and the place of examination are divided. Thus the CISG, the Common Law System and the Civil Law System including Korean Law stipulate the buyer's examination at the destination if the sales contract involves carriage of the goods. This author, from the buyer's perspective, would like to make the following suggestions in regard to the time of examination when the sales contract is made. First, the time of examination and the time of quality decision should be in accord, even though the time of delivery is different. Second, the buyer should clearly indicate the time, the place, the inspector, the particulars and the burden of proof in regard to examination when contracting. Third, the buyer should also clearly indicate the period of notice for the lack of conformity in Claim Clause of sales contract, which should be counted from the time of examination. Fourth, the buyer should remember that he many lose the right to rely on the lack of conformity of the goods if he does not give the seller notice thereof within the stipulated time or reasonable time. Finally, if the buyer wants, to examine the goods at the place of shipment, it is desirable for the buyer to designate internationally recognized inspection organization like SGS.
Design and Implementation of a Photo Detector Using a Complementary Metal-Oxide Semiconductor
오원석,박강엽 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.61
In this paper, we present a photo detector using a complementary metal-oxide semiconductor (CMOS) for plastic optical fiber (POF) applications. Generally, the PIN photodiode and optical receiver front-end circuit are made from III-V compound materials, such as GaAs, InP, and HEMT (High Electron Mobility Transistor), due to their high speed and low noise characteristics. However, silicon deep-submicron CMOS technology is more attractive due to its low cost and high integration capacity. A PIN photodiode using a CMOS suffers from a low responsivity (R) a slow spreading speed of drift and diffusion current generated by photon. To overcome the low responsivity of the CMOS PIN photodiode, we exploit a PN junction between the N-well and the P-substrate. We propose a finger-shaped arrangement of the P-substrate to compensate for the slow spreading speed of the drift currents. The implemented CMOS PIN photodiode exhibits 0.12-A/W responsivity and 4.5-pF parasitic capacitance. Also, the optical receiver front-end circuit for the POF applications is integrated with the CMOS PIN photodiode. The designed photo detector exhibits a 112-MHz 3-dB bandwidth and consumes only 3-mA of DC current from a single 3.3 V supply voltage.

The purpose of this study is to establish experimental canine skin barrier disruption model in dog. The study was designed to investigate the predictive properties of acetone damage using as effect parameters transepidermal water loss (TEWL) and stratum corneum (SC) hydration. To compare the structures of SC intercellular lipids in normal and acetone damaged skin, TEM observations were performed. Six clinically normal, male Beagles without dermatological problems were chosen for this study. Acetone damage was performed at 48hrs after clipping. Efficacy measurements for TEWL and skin hydration were performed before (t1) and after (t2) damage in a temperature- and humidity-controlled room (20-22oC, 50-60%). TEWL and SC hydration values were decreased in the acetone damaged model compared with non damaged skin. In TEM observation of acetone damaged sample, the intercellular lipid lamellae exhibit abnormal and incomplete structure compared with those of normal skin. It seems that acetone damage would be one of canine skin epidermal barrier disruption model for the study of canine atopic dermatitis (AD) as well as dry skin in veterinary dermatology research.
Visual Imaging of Calcium Ion Distribution in Acetone and Tape Stripping Damaged Canine Epidermis
오원석,이근우,오태호 한국임상수의학회 2010 한국임상수의학회지 Vol.27 No.3
The purpose of this study is to establish experimental canine skin barrier disruption model, the study was designed to observe calcium ion in skin frozen tissue of canine skin and also the modulation of calcium ion distribution of normal skin with disrupted skin such as clipping, acetone, tape stripping damages according to time. To compare the changes of calcium ion gradient after damages, the distribution of calcium ion in the canine epidermis was visualized by blotting to gel containing chemical indicator (Calcium Green-1) with fluorescent microscope and the effects of skin barrier damages were examined according to time. Three mins and 1hr after acetone damage, the gradations of epidermis and hair follicle showed more radiant and disappeared after 48 hrs. On the contrary, 3mins and 1hr after tape stripping damage, the gradations showed more radiant than those of acetone damage, and these gradations were stabilized after 48 hrs. The method we presented here could show the visual image of the calcium ions in frozen tissue without further preparation, and it might be useful to investigate the role of calcium ion in the canine epidermal barrier recovery, however, it might be need further methodological improvement to get accurate quantitative information.

This Comment explores the ICSID case of CMS Gas Transmission Company v. Argentine Republic, awarded on May 12, 2005. The Part II of this Comment first describes the relevant facts of the case including the some background for readers' understanding and the Part III summaries the claimant's requests and the decisions rendered by the Arbitral Tribunal in the Award. At Part IV, the Comment addresses the issue of determinating laws applicable to the merits of dispute in case that the parties of the case have not chosen a governing law, and at Part V, takes a close look into three main issues of (i) the indirect expropriation of the investment, (ii) the breach of fair and equitable treatment and (iii) the protections under umbrella clauses. In this CMS case, we see first that while the Tribunal affirmed that any indirect expropriation can occur from incidental interference depriving the foreign investor of the use or reasonable-to-be-expected economic benefit even if not necessarily to the obvious benefit of the host State, the Tribunal denied the occurrence of indirect expropriation in this case by holding that the Government of Argentina has not breached the standard of protection laid down in the Treaty. Secondly, however, regarding the issue of fair and equitable treatment, we see that the Tribunal, finding Argentina's breach of obligations, affirmed that the foreign investor can expect the host State to act in a consistent manner, free from ambiguity and totally transparently in its relations with the foreign investor, which can give the foreign investor certain degree of foreseeability. Thirdly and finally, we see that, on base of the effect of the umbrella clause, the Tribunal recognized the obligation of the host State undertaken not to freeze the tariff regime or subject it to price controls and not to alter the basic rules governing contracts between the foreign investor and the host State without the first's written consent. However, the protection under the umbrella clause is available only when there is a specific breach of rights and obligations under BIT or a violation of contract rights protected under BIT.
